Is My Car Worth Less After an Accident?

Usually, yes. A car that has been in an accident is often worth less than an identical car with a clean history, even after a good repair. How much less depends on how serious the damage was, the quality of the repair, whether the car was recorded as an insurance write-off, and how well the work is documented.

Why does an accident reduce a car's value?

Many buyers worry about hidden damage or poor repairs, so they offer less for a car with accident history, or avoid it altogether. The loss in value after a repair is sometimes called diminution in value.

What affects how much value is lost?

• Severity of the damage. A scuffed bumper is very different from damage to the car's structure.

• Quality of the repair. Repairs done properly, with the right parts and paperwork, help buyers feel confident.

• Write-off category. Cars recorded as an insurance write-off usually lose more value.

• Age, mileage and type of car. The effect can be larger on newer or more valuable cars.

What do the write-off categories mean?

• Category A: scrap only. The car cannot return to the road and no parts can be reused.

• Category B: the body must be crushed, but some parts can be salvaged.

• Category S: structural damage that has been, or can be, repaired.

• Category N: non-structural damage that has been, or can be, repaired.

Category S and N cars can be repaired and driven again, but the category stays on the car's record. Our guide to Cat S and Cat N cars explains what to check if you are buying one.

Do I have to tell a buyer my car has been in an accident?

You must not misdescribe the car you are selling. If you are asked about accident damage, answer honestly, and do not hide a write-off category. Giving false information can leave you open to a claim from the buyer. Being open from the start, with repair invoices to hand, usually makes selling easier.

Can I claim for the loss in value?

If the accident was not your fault, you may be able to claim for the drop in your car's value as part of a claim against the other driver's insurer. Ask your insurer or a solicitor for advice, as this depends on the circumstances. Our guide on what to do after a car accident covers the first steps.

How can I protect my car's value after an accident?

1. Use a reputable repairer and keep every invoice and photo.

2. Check the repair before you accept the car back, including panel gaps, paint match and warning lights.

3. Have safety systems checked, as cameras and sensors may need recalibrating after body repairs.

4. Keep the service history up to date so the rest of the car's record is strong.

Common questions

Will an accident show up on a history check?

Insurance write-offs usually show on a vehicle history check. Minor accidents that were not claimed for may not appear.

Is it worth buying a Category N car?

It can be, if the price reflects the history and the repair has been done properly. Get it inspected and check your insurer will cover it.

Does a small repair affect value?

Minor cosmetic repairs done well usually make little difference, especially if you have the paperwork.
